Troubleshooting Performance Issues

Atlas Is Slow on Every Device

Symptom: Pages load slowly or the interface lags on every device, including the host computer.

Solutions:

1. Memory: Atlas needs at least 4 GB of RAM on the host computer, and more is recommended, as listed in System Requirements. On Docker Desktop, check that its memory limit under Settings => Resources is not set below the requirement.
2. Other programs: Close programs on the host computer that use a lot of processor time or memory.

Automatic Alignment Is Slow

Symptom: Aligning images in a comparison takes a long time.

Solution: Automatic alignment is resource-intensive. Align fewer images at a time, and avoid aligning while the host computer is busy with other work.

Atlas Is Slow on Wireless Devices

Symptom: Atlas is responsive on the host computer but slow on tablets and laptops.

Solutions:

1. Connect the host computer to the network by cable. This keeps the host computer off the Wi-Fi network and leaves more wireless capacity for the other devices.
2. Move the device closer to the Wi-Fi access point, or use a 5 GHz network where available.

Image Upload Is Slow

Symptom: Uploading images takes a long time.

Solutions:

1. Network: Large uploads depend on the Wi-Fi speed of the device. Move closer to the access point, or upload from a computer connected by cable.
2. Batch size: Upload smaller batches. A single upload takes up to 50 images.
3. Disk space: Check that the host computer has ample free disk space.

For uploads that fail rather than run slowly, see Troubleshooting Image Storage Issues.
